lllhe object of my invention is to thresh, clean, measure, tally, and sack grain automatically; and

'It consists in the arrangement and combination of the grain-elevator, the receiving and measuring-box, the/'bag or sack-holders, and the tallying-mechanism; also, the construction of the shoe and tailing-board, the frame for holding the sieve, the conducting-board, and mode of operating the same.

To enable others to make and use my invention, I will describe it more in detail, referring to the drawings, and to the letters marked thereon.

I make or use threshingemachines constructed in any of the most approved styles, as seen in figs. 1 and 9,

in which I arrange my improved sieve-frame a a, and

H, constructed 1n the manner herein described.

grain-conducting board A. p

There may be iianges, a a, on the sides of the frame, or the grain may be kept from iiowing'over the edges of the sieve, or screen, B, by attaching cloth, or other substance sufficiently flexible to allow the frame to vibrate from side to side, under which screen and frame is placed the shoe or movable` board D, which serves to conduct the grain to the elevator E.

On the upper end of the shoe D isthe spout C to receive thetailings, or refuse grain, and conduct it to the elevator F, to run through the machine again.

The `v`screen, or cleaning-apparatus, vibratcs between the boards b b, made stationary to the frame G.

In the ends of the boards b is itted in grooves the tailing-board d, so that itcan be adj usted up or down, as may be required.

The elevator E is so placed in the side ofthe machine, that it receives the grain from the shoe D, and conveys it to the measuring-box H, which is constructed with two compartments, lt 7L, of equal dimensions.

The bottom of the measuring-box His composed of stili' leather, I I, fastened to the centre, as seen in Iig. 2. The b'ox H is made to slide on a frame to bring each compartment alternately under the upper end of the grain-elevator E, to receive the contents as they are `being discharged. When the compartment at oneend is filled, the box slides and brings it over the mouth of one of the bags or sacks, g, and the weight of .the grain depresses and opens the bottom, I, and passes through into the sack. At the same time the other compartment is being filled, when the box slides the other way and deposits the grain iu the other bag, g', in the same manner; and so alternately the measures are being iilled and emptied into bags, while the threshing and cleaning-process is going on.

There may be a tallying and registering-apparatus attached to the machine, and worked by the alternate sliding of the measuring-compartments, so that the number of bushels threshed and sacked up may be known, without keepingcount.

Thebags, or sacks, g g', are attached to the frame K by spring-levers k 7c, which yclamp the open ends of the bags on to ledges j j on the frame K, where they are iirmly held, to be illed, by the action of the hooks t' i '1'. in the bar J, in which the upper or long portion of the levers k k is placed.

The main belts, m n, of the threshing-machine and separator, are covered by a cap or shield, M, to protect them fromthe sun and weather.

Having thus fully described my invention,

What I claim as new, and desire to secure by Letters Patent, isf- 1. The receiving, measuring, and discharging-box,

2. In combination with the boX H, the elevator E, the frame K, clampflevers k k, hook-bar J, and bags g gf, substantially as and for the purposes set forth.

3. rlhe sieve-frame, with its iianges a a, or clothattachments, to prevent the overflow at the sides, when connected with the shoe D, spout (l, and tailing-board D, -as and for the purposes herein specified.
